A composite cost model for the aeronautical industry: Methodology and case study

This paper presents a novel composite production cost estimation model. The strength of the model is its modular construction, allowing for easy implementation of different production methods and case studies. The cost model is exemplified by evaluating the costs of a generic aeronautical wing, consisting of skin, stiffeners and rib feet. Several common aeronautical manufacturing methods are studied. For studied structure, hand layup is the most cost-effective method for annual volumes of less than 150 structures per year. For higher production volumes automatic tape layup (ATL) followed by hot drape forming (HDF) is the most cost-effective choice.     

Effect of different soaking and germination methods on bioactive compounds of germinated brown rice

Germination of brown rice can be completed by full soaking and partial soaking methods. This study aimed to analyse the influence of germination methods on the bioactive accumulations in germinated brown rice (GBR). Germination was conducted in four treatments: (i) membrane reactor with full (RFS) and (ii) partial soaking method soaking (RAG), (iii) manual soaking for complete germination (MFS) and (iv) partial manual soaking in combination with atmospheric germination (MAG). The results showed that soaking BR in membrane reactor accelerated the shoots' growth and increased GABA (γ-aminobutyric acid) content compared with the manual soaking method. The RAG treatment achieved higher GABA content (up to 125 mg/100 g), total phenolic and flavonoid content, and antioxidant activity than other germination methods. The main finding of this research indicates that membrane reactor effectively enhances the growth of sprouts. The combination of partial soaking in membrane reactor and atmospheric germination (RAG) is a suited method to increase GABA accumulation in GBR.
